Take it you are willing to believe (6)
I believe the answer is:
accept
This might be a double definition.
'take it' is the first definition.
(thesaurus)
'to believe' is the second definition.
(I've seen this before)
'you are willing' acts as a link.
This may not be correct. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for accept that I've seen before include "Bear" , "Take -- consent" , "Believe to be correct; take on" , "Agree or be willing to take" , "Believe to be valid" .)
